Author: Reece Thompson | Updated on March 7, 2021

Costing less than a meal out, these could be a life saver - especially if you have a number of gas appliances. We review 5 of the most reliable ones.

A gas leak is scary and dangerous. If you've ever seen the panic on the face of a person when the smell hits their nose, then you'll know what I mean.

It is even more frightening if you cannot detect where the leak is coming from. For a split second, you won't know whether to run, call the fire department or attempt to locate the problem yourself.

As funny as it sounds, people have lost their entire livelihoods because of gas leaks. The Merrimack Valley gas explosions stand as a reminder. They often lead to combustible gases seeping into the atmosphere and buildings.

At this point, the slightest spark could set off a hazardous explosion. This is what led to the invention of the devices described on this page. It is an alarm system that can determine how much gas has filled the room.

This will help you to decide whether you need to exit the building or the gas is still at a safe level to investigate. In this article today, we will be looking at five of the top products available to the general public i.e. not commercial types.

We will examine and review these products to figure out which of them is the best. We will find relevant information to make a great decision on what is best for you.

FAQ and Buying Guide

What makes a good or bad device?

First, we will be looking at a few of the most important questions to ask when you want to buy a gas monitor.

Is it an automatic or manual system?

You want to buy one that suits your lifestyle. There are two different types of gas monitors that you can buy:

You can either get automatic or portable gas detection device. These two have quite distinct and separate advantages.

If you decide that you want an automatic system, it will have to be somewhere in your house. They tend to drill it into the wall close to a power supply.

It will only be able to detect vapours that have got into that part of the house. At which point, an alarm will alert you.

It serves as a tremendous preventative mechanism. The gas leak detectors come with predetermined hazardous levels.

Anything outside of the set parameters will cause an alarm. The main disadvantage of this product is that you will not determine the location of the gas leak. You will only be able to tell the concentration of gas levels in the area.

If you decide to go with a manual system, you will usually need batteries as a power supply. This option is portable. It will be a handheld device that has a nozzle.

This is useful for people that perform leakage detection as a career. These people include but are not limited to firefighters and plumbers. We like this product because it can detect the location to a high degree of accuracy.

It does so by finding out where the gas’s biggest concentration is coming from and directing you there. This will be useful for finding leakage in locations that are difficult to access. These may include areas such as the wall, the roof, or underground

What gases can they pick up?

Many different types can be harmful when inhaled. You must diagnose any of these that may be lingering around the house.

When you buy a new device, you must ensure that you have checked what gases it can pick up. The main three are combustible gases, carbon monoxide, and radon.

Radon is the most difficult for the human nose to detect. People can live with it for many years without realizing they exist. They're linked as the second leading cause of lung cancer.

Carbon monoxide are those that come from a running machine. So, if you have a generator in the house that you may use, these gases may remain and cause you lung trouble.

The combustible gases are dangerous because they are natural. If they are leaking, it can lead to an explosion and likely burn down the house.

Portability vs Installation?

You need to know what you are looking for. If you want to buy the portable version, you must know that this product will not function as an alarm. It is a reactive tool.

This means that you will need to turn it on to determine gas levels in the house. It is helpful because it can detect where the location of the leakage is.

If you decide that you want to buy the installed version, you will not detect where the location of the gas leak is. With this, you will receive an alarm when gas levels in the house have reached a certain level.

It is quite a complicated question because both are very useful. If you have extra money, you might consider getting both.
